A vehicle cleaning device includes a cylinder to which a cleaning fluid is supplied; a piston slidably inserted in the cylinder; a spray nozzle unit mounted at a leading end of the piston and configured to spray the cleaning fluid toward an object-to-be-cleaned; and a cap that closes a gap between the cylinder and the piston in an opening of the cylinder through which the piston protrudes. The cap includes a tubular part inside the cylinder, and the tubular part defines an end of movement of the piston. A communication hole is provided between a communication groove provided in an outer peripheral surface of the tubular part and an inner peripheral surface of the cylinder, and the gap between the cylinder and the piston communicates with the outside of the cylinder through the communication hole.
